Description of the Related Art Among tabletop appliances, various table tops, sinks, bathroom units, lighting equipment and the like made of synthetic resin molded products have many cast molded products provided with surface decoration. This type of resin casting is made by filling a resin with a coloring material having a dye, a pigment, gloss, and the like and molding the resin. Until now,
What has been used as a filler colorant with gloss,
There are mica, glass, pearl oyster powder, aluminum filler, etc., all of which have high specific gravity. For this reason, in consideration of the dispersibility of the filler in the resin composition at the time of molding and the physical properties of the cast product, the filler colorant is limited to those having a small particle diameter. On the other hand, the scale-like titanium coloring material that develops color by the light interference effect has better coloring as the particle size is larger. Therefore, if it can be used as a filling coloring material, the decorative effect is expected to increase.

い、装飾効果に劣り、好ましくない。However, since the titanium coloring material has a specific gravity of about 4.5 and is larger than the above-mentioned filling coloring material, it is more difficult to sufficiently uniformly disperse it in the resin composition. It is. In particular, when a flaky titanium coloring material having a large particle size is used as the filling coloring material, in addition to having a large specific gravity, unevenness is likely to occur during injection into a mold due to its shape, and workability is increased. And a problem that has not been encountered when a glossy filler having a relatively small particle size and a gloss is used. Further, in order to sufficiently develop the flaky titanium coloring material which is colored by the light interference effect, the flaky titanium coloring material is distributed without gaps on the surface layer of the synthetic resin molded product, and the flaky titanium coloring material is coated on the surface. Are required to be arranged in parallel. Even if the dispersibility in the resin composition is improved in order to satisfy this requirement, simply improving the dispersibility disturbs the reflection surface of the particles, and is inferior in decorative effect, which is not preferable.

This is a decoration method of a cast product 17 using a titanium coloring material. When the viscosity of the resin is reduced by heating the horizontal mold, the titanium color material sinks toward the inner surface of the lower glass plate by its own weight. Due to the electrostatic repulsion caused by the substituents of the titanate compound on the surface of the titanium color material, the titanium color material rearranges near the inner surface of the lower glass plate to form a layered titanium color material layer without gaps. Here, since the surface potential of the titanium coloring material and the surface potential of the lower glass plate are the same, the precipitated titanium coloring material does not reach the inner surface of the glass plate. When the polymerization of the thermosetting resin is completed in this state, a decorative resin cast product having a titanium coloring material layer in which the flaky titanium coloring material is arranged in a layer without gaps is obtained.

A urea resin, an unsaturated polyester resin, a linear polymer melt, a monomer, or an initial polymer (for example, an acrylic resin) is used. The amount of the flaky titanium coloring material to be added to the casting resin is determined by the expected performance of the resin casting product, but is usually 0.1 to 5.0% by weight based on the total weight of the casting resin. It is. The amount is sufficient to cover the surface layer portion of the resin casting with the titanium color material layer having no gap. Too much wastes color materials and increases costs.

無は目視により評価する。First, a flaky titanium coloring material surface-treated with a titanate-based compound is mixed and uniformly dispersed in a thermosetting resin solution as a casting resin. Then Figure 1
As shown in (a), a mold was assembled by sandwiching an annular gasket (not shown) around the two tempered glass plates 11 and 12 facing each other, and a mold 13 was obtained. After removing a part (not shown) of the gasket, a thermosetting resin solution 15 in which the flaky titanium color material 14 is dispersed is injected. At this time, the viscosity of the thermosetting resin solution is preferably in the range of 1 to 20 poise. Preferably it is 5 to 15 poise.
At 1 poise or less, the flaky titanium coloring material having a large specific gravity immediately sinks and tends to become uneven. At 25 poise or more, it takes a long time to inject, and the workability is not good. A part of the removed gasket is returned to its original state, and the mold 13 is heated while the glass surface is kept horizontal as shown in FIG. The flaky titanium coloring material 14 which has been uniformly dispersed in the resin solution until then
When the resin solution 15 is heated, the viscosity of the resin solution once decreases, so that the resin solution 15 precipitates by its own weight and rearranges due to electrostatic repulsion caused by the substituent of the titanate compound which is a surface treatment agent. A layered titanium color material layer 16 having no gap is formed on the surface layer of the mold. Here, since the surface potential of the titanium color material is the same minus as the inner surface potential of the glass plate 12, the titanium color material layer 16 repels the glass plate 12 and does not adhere to the glass plate 12. As the heating proceeds, the polymerization of the thermosetting resin is completed. After the heating is stopped, the resin solution is cured by cooling, and the mold 13 is removed.
Is obtained. This resin cast product 17 has a resin thin film 17 on its surface.
is formed, and under the resin thin film 17a, a titanium coloring material layer 16 in which the flaky titanium coloring material 14 is arranged in a layered manner without gaps is formed. The degree of dispersion of the flaky titanium coloring material in the cast product is evaluated by measuring the spectral transmittance of the cast product. Further, the coloring property of the flaky titanium coloring material, and the presence or absence of peeling and flaws are visually evaluated.

The color of the flaky titanium coloring material is good,
A molded product with a unique decorative effect was created. In addition, since the surface layer was covered with the resin thin film, the titanium color material layer was not peeled off even when the surface of the acrylic cast product was repeatedly rubbed with a polishing cloth.
However, in the cast products made from the resin solutions of Comparative Examples 1 and 2, the unevenly distributed surface of the flaky titanium coloring material is unlikely to come off the mold, and even if it comes off, the cast product remains in the mold. As a result, the appearance was severely impaired as compared with Examples 1 and 2, for example, by peeling off parts. When the surface of the acrylic cast product was repeatedly rubbed with a polishing cloth, the flaky titanium coloring material came off. In addition, in the cast product made from the resin solution of Comparative Example 3, the titanium color material layer was not peeled off even when the surface of the cast product was repeatedly rubbed with a polishing cloth, but the flaky titanium color material was found in the cast product. Was distributed not only on the surface layer but also on the entire surface, so that the reflection surface of the flaky titanium coloring material was disturbed. Therefore, the color of this cast product was darker than those of Examples 1 and 2.

This cast product has a unique decorative effect that emerges as a result of lighting, and has the feature that physical and mechanical properties do not vary. Also, since the amount of expensive flaky titanium coloring material can be minimized, it is also excellent in economical efficiency.
